Liu Q, Wang Y, Tan L, Ma W, Zhao X, Shao C, Wang Q. The Role of the Heat Shock Cognate Protein 70 Genes in Sex Determination and Differentiation of Chinese Tongue Sole ( Cynoglossus semilaevis). Int J Mol Sci 2023; 24:ijms24043761. [PMID: 36835170 PMCID: PMC9964925 DOI: 10.3390/ijms24043761] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 02/03/2023] [Accepted: 02/06/2023] [Indexed: 02/16/2023] Open
Abstract
Fish sex determination can be affected by environmental temperature. This process relies on temperature-sensitive proteins such as heat shock proteins (HSPs). Our previous work found that heat shock cognate proteins (HSCs) may participate in high-temperature associated sex reversal of Chinese tongue sole (Cynoglossus semilaevis). However, the role of hsc genes in responding to high temperature and affecting sex determination/differentiation remains unclear. Here, by using C. semilaevis as model, we identified hsc70 and hsc70-like. hsc70 was abundant in the gonads with a testicular-higher expression at all gonadal development stages except for 6 months post fertilization (mpf). Intriguingly, hsc70-like showed higher expression in testes from 6 mpf on. Both long-term heat treatment during the temperature-sensitive sex-determining period and short-term heat stress at the end of this period caused different expression of hsc70/hsc70-like between sexes. The dual-luciferase assay results also suggested that these genes can respond to high temperature rapidly in vitro. Heat treatment of C. semilaevis testis cells overexpressed with hsc70/hsc70-like could affect the expression of sex-related genes sox9a and cyp19a1a. Our results indicated that hsc70 and hsc70-like were key regulators linking external high-temperature signals with sex differentiation in vivo and provide a new idea for understanding the mechanism by which high temperature affects sex determination/differentiation in teleosts.

Impact of Aeromonas hydrophila and infectious spleen and kidney necrosis virus infections on susceptibility and host immune response in Chinese perch (Siniperca chuatsi). FISH & SHELLFISH IMMUNOLOGY 2020; 105:117-125.

Abstract
Co-infections with pathogenic microorganisms are common in aquaculture, resulting in more serious economic losses than single-pathogen infection. Infection of Aeromonas hydrophila (A. hydrophila) often occurs together with infectious spleen and kidney necrosis virus (ISKNV) in Chinese perch (Siniperca chuatsi) culture ponds. In this study, A. hydrophila and ISKNV were inoculated into Chinese perch to mimic individual infection, secondary infection, and mixed infection. The effects of concurrent infections on the susceptibility and the immune response of the host and changes in bacterial and viral load were studied. The results showed relatively complex interaction between ISKNV and A. hydrophila for different infection modes, acting in an antagonistic or synergistic manner. The experimental groups infected with a mixture of ISKNV and A. hydrophila showed higher mortality rate than groups infected with single-pathogen or secondary infection groups, suggesting a synergistic lethal effect of A. hydrophila and ISKNV co-infection. Serious clinical symptoms and obvious histopathological changes were observed in moribund fish under the mixed-infection condition. In addition, obviously higher mortalities were caused by secondary bacterial infections than the number caused by secondary viral infections. ISKNV-primary infection increased the mortality caused by secondary bacterial infections, but A. hydrophila-primary infection did not significantly increase the mortality caused by secondary viral infections. Co-infected fish showed high expression levels of IRF1, Mx, Viperin, Hepcidin, TNFα, and IL-1β mRNAs relative to the levels in healthy fish, which suggested that the co-infection of these two pathogens activated the host immune system and caused host inflammation. These results of infection with A. hydrophila and ISKNV provided the theoretical basis to analyze the pathogenic effects and interaction between pathogens, and could facilitate design of strategies for clinical prevention and control measures of outbreak of fulminant hemorrhagic disease and bacterial sepsis in Chinese perch.

Abstract
As molecular chaperones, heat shock proteins (HSPs) play essential roles in cells in response to stress conditions. Recent studies about immune functions of HSPs in fish have also been reported. In this study, based on the reported cDNA sequences of the four HSP genes, HSP70, HSC70, HSP90α and HSP90β, the temporal expression patterns of the four genes during embryonic development of dojo loach(Misgurnus anguillicaudatus) was assayed with qRT-PCR. All of the four genes were ubiquitously expressed in all detected embryonic developmental stages. Among of them, HSP70, HSC70 and HSP90β were highly expressed in the organ formation stage, while HSP90α was the highest expressed in myotome formation stage. Further, the immune responses of the four HSP genes were assayed when loach were infected with three different pathogens, bacterium (Flavobacterium cloumnare G4), parasite (Ichthyophthirius multifiliis) and fungus (Saprolegnia). All of the four genes were differentially expressed in four tissues such as skin, gills, spleen and kidney in response to the pathogenic invasion, but both HSP70 and HSP90α expressions were dramatically up-regulated. Further, the cellular responses of the loach skinand gill tissues were observed, in which the number of the skin goblet cells were significantly increased, and the gill lamellae became shorter and wider after infected. Thus, our work indicated that the HSPs may directly or indirectly involved in immune defense in fish, at least in the loach.

Abstract
Mandarin fish (Siniperca chuatsi) is a universally farmed fish species in China and has a large farming scale and economic value. With the high-density cultural mode in mandarin fish, viral diseases, such as infectious spleen and kidney necrosis virus (ISKNV) and Siniperca chuatsi rhabdovirus (SCRV), have increased loss, which has seriously restricted the development of aquaculture. Y-Box binding protein 1 (YB-1) is a member of cold shock protein family that regulates multiple cellular processes. The roles of mammalian YB-1 protein in environmental stress and innate immunity have been studied well, but its roles in teleost fishes remain unknown. In the present study, the characteristic of S. chuatsi YB-1 (scYB-1) and its roles in cold stress and virus infection were investigated. The scYB-1 obtained an 1541 bp cDNA that contains a 903 bp open reading frame encoding a protein of 300 amino acids. Tissue distribution results showed that the scYB-1 is a ubiquitously expressed gene found among tissues from mandarin fish. Overexpression of scYB-1 can increase the expression levels of cold shock-responsive genes, such as scHsc70a, scHsc70b, and scp53. Furthermore, the role of scYB-1 in innate immunity was also investigated in mandarin fish fry (MFF-1) cells. The expression level of scYB-1 was significant change in response to poly (I:C), poly (dG:dC), PMA, ISKNV, or SCRV stimulation. The overexpression of scYB-1 can significantly increase the expression levels of NF-κB-responsive genes, including scIL-8, scTNF-α, and scIFN-h. The NF-κB-luciferase report assay results showed that the relative expression of luciferin was significantly increased in the cells overexpressed with scYB-1 compared with those in cells overexpressed with control plasmid. These results indicate that scYB-1 can induce the NF-κB signaling pathway in MFF-1 cells. Overexpressed scYB-1 can downregulate the expression of ISKNV viral major capsid protein (mcp) gene but upregulates the expression of SCRV mcp gene. Moreover, knockdown of scYB-1 using siRNA can upregulate the expression of ISKNV mcp gene but downregulates the expression of SCRV mcp gene. These results indicate that scYB-1 suppresses ISKNV infection while enhancing SCRV infection. The above observations suggest that scYB-1 is involved in cold stress and virus infection. Our study will provide an insight into the roles of teleost fish YB-1 protein in stress response and innate immunity.

Expression pattern of heat shock protein 90AB (HSP90AB) and stress-inducible protein 1 (Stip1) during spermatogenesis of mudskipper Boleophthalmus pectinirostris. Comp Biochem Physiol B Biochem Mol Biol 2019; 231:42-51.

Abstract
Heat shock protein 90 (HSP90), which functions as a molecular chaperone, plays an important role in reproduction and cellular defense. Among the HSP90 family, HSP90AB is an important isoform. Stress-inducible protein 1 (Stip1) acts as a co-chaperone that mediates interactions with HSP90 and appears to be a player in spermatogenesis and stress response. However, the functions of both HSP90 and Stip1 during spermatogenesis and heat stress response in Boleophthalmus pectinirostris remain unknown. We investigated mRNA expression patterns of HSP90AB and Stip1 under heat stress conditions. The results showed that mRNA levels of HSP90AB and Stip1 were significantly upregulated in the gill and liver tissues, indicating that HSP90AB and Stip1 appear to play roles in protection against heat stress. Then we cloned the complete cDNA of HSP90AB and Stip1, which have product lengths of 2546 and 2652 bp, respectively. The predicted secondary and tertiary structures of B. pectinirostris. HSP90AB and Stip1 contain conserved domains. We investigated the expression patterns of HSP90AB and Stip1 in different tissues by quantitative real-time polymerase chain reaction, HSP90AB and Stip1 were found to be ubiquitously expressed in all major tissues and exhibited varying expression levels, indicating that HSP90AB and Stip1 have conserved biological functions. HSP90AB and Stip1 were found to be strongly expressed in the testis, indicating their special roles in this organ. We also tracked the dynamic locations of germinal cells using in situ hybridization. Results from in situ hybridization and immunofluorescence localization showed that both mRNA transcripts and proteins of HSP90AB and Stip1 were ubiquitously expressed in spermatocytes, spermatids, and spermatozoa, indicating that HSP90AB and Stip1 are both involved in spermatogenesis.

Abstract
Peptidylarginine deiminases (PADs) are calcium dependent enzymes with physiological and pathophysiological roles conserved throughout phylogeny. PADs promote post-translational deimination of protein arginine to citrulline, altering the structure and function of target proteins. Deiminated proteins were detected in the early developmental stages of cod from 11 days post fertilisation to 70 days post hatching. Deiminated proteins were present in mucosal surfaces and in liver, pancreas, spleen, gut, muscle, brain and eye during early cod larval development. Deiminated protein targets identified in skin mucosa included nuclear histones; cytoskeletal proteins such as tubulin and beta-actin; metabolic and immune related proteins such as galectin, mannan-binding lectin, toll-like receptor, kininogen, Beta2-microglobulin, aldehyde dehydrogenase, bloodthirsty and preproapolipoprotein A-I. Deiminated histone H3, a marker for anti-pathogenic neutrophil extracellular traps, was particularly elevated in mucosal tissues in immunostimulated cod larvae. PAD-mediated protein deimination may facilitate protein moonlighting, allowing the same protein to exhibit a range of biological functions, in tissue remodelling and mucosal immune defences in teleost ontogeny.

Abstract
Heat shock proteins 70 (HSP70s) are molecular chaperones that aid in protection against environmental stress. In this study, we cloned and characterized five members of the HSP70 family (designated as HSPa1a, HSC70-1, HSC70-2, HSPa4 and HSPa14) from Lateolabrax maculatus using rapid amplification cDNA ends (RACE). Multiple sequence alignment and structural analysis revealed that all members of the HSP70 family had a conserved domain architecture, with some distinguishing features unique to each HSP70. Quantitative real-time (qPCR) analysis revealed that all members of the HSP70 family were ubiquitously and differentially expressed in all major types of tissues, including testicular tissue. This indicated that HSP70s have vital and conserved biological functions, and may also function in the development of germinal cells. The expression of mRNA of the five HSP70 family members mRNA expression was significantly increased in the head kidney, intestine and gill after Vibrio harveyi challenge, suggesting that HSP70s play an important role in the immune response.

Abstract
Heat shock proteins (HSPs) are highly conserved molecular chaperones that play critical roles in both innate and adaptive immunity. However, little information about HSPs from marbled eel Anguilla marmorata is known. In this study, the full-length Amhsp90 (2527 bp), Amhsp70 (2443 bp) and Amhsc70 (2247 bp) were first cloned from A. marmorata, using rapid amplification of cDNA ends, containing open reading frames of 2181, 1932 and 1950 bp in length, and encoding proteins with 726, 643 and 649 amino acids, respectively. The deduced amino acid sequences of three Amhsps shared a high homology similarity with other migratory fish. Real-time fluorescent quantitative polymerase chain reaction was used to evaluate tissue-specific distribution and mRNA expression levels of three Amhsps subjected to infection with Aeromonas hydrophila. The mRNA expression of three Amhsps in eight tested tissues, namely liver, heart, muscle, gill, spleen, kidney, brain and intestine, of juvenile A. marmorata was evaluated to reveal the major expression distribution in liver, intestine, muscle and heart. After pathogen challenge treatments, mRNA transcriptions of three Amhsps revealed a significant regulation at various time points in the same tissue. All these findings suggest that Amhsps may be involved in the immune response in A. marmorata.

Abstract
HSP90 plays important roles in multiple cellular stress responses. Here, two cytoplasmic HSP90 isoforms, ScHSP90α and ScHSP90β, were identified from Siniperca chuatsi. Their cDNA and gDNA structures, amino acid sequence features, and sequence identities and phylogenetic analysis with other species were described. Their expression profiles during embryonic development in different tissues and under stressful conditions were analyzed using real-time quantitative PCR. During embryogenesis, transcripts of both genes were detected at low levels during the early developmental stages and were up-regulated from appearance of myomere for ScHSP90a and closure of blastopore for ScHSP90β. ScHSP90α showed a tissue-specific variation with high expression in ovary and brain under non-stressed conditions, while ScHSP90β was ubiquitously highly expressed in different tissues. Acute heat shock resulted in a strong up-regulation of ScHSP90α in heart, liver, and head kidney, while it only weakly induced ScHSP90β in these tissues. ScHSP90α was also markedly induced in liver in a time-dependent manner under hypoxia, while the expression of ScHSP90β was not affected by hypoxia. Additionally, Aeromonas hydrophila infection markedly augmented ScHSP90α in head kidney and spleen and mildly up-regulated ScHSP90β in spleen, while suppressing ScHSP90β in head kidney. These results suggest that ScHSP90α and ScHSP90β are differently involved in embryogenesis and under different environmental conditions including high temperature, hypoxia, and bacterial infection. This study will benefit to further clarify the roles of fish HSP90 isoforms in embryogenesis and under stressful conditions and contribute to further study on enhancing stress tolerance and disease resistance of mandarin fish.
